Do you estimate environmental impact savings?

Reading through my rss feed this morning, and found a great post on the paper life cycle from the Greenprinter Blog. I admit, when it comes to client projects (usually constrained by time and money), I don’t consider the environmental impact of the printed product I am buying on their behalf. After watching this short video from Inform Inc., I’m thinking that we need to take more time to investigate recycled options and include the estimated savings to environmental impact to print project quotes.

What do you think? Do you include this info now? Do clients care?

Know of any great environmental impact calculators out there for print buyers? Please let me know.
